• XON-XON
• Data transmission control
Software handshaking is performed between the MV and the PC. When an “X-OFF”
code is received while sending data to the PC, the MV stops the data transmission.
When the next “X-ON” code is received, the MV resumes transmission. The MV
ignores the CS signal that is received from the PC.
• Data reception control
Software handshaking is performed between the MV and the PC. When the used
area in the received buffer increases to 1537 bytes, the MV sends an “X-OFF”
code. When the used area decreases to 511 bytes, the MV sends an “X-ON” code.
RS = True (fixed).
• XON-RS
• Data transmission control
The operation is the same as with XON-XON.
• Data reception control
Hardware handshaking is performed between the MV and the PC. When the used
area in the received buffer increases to 1537 bytes, the MV sets “RS=False.” When
the used area decreases to 511 bytes, the MV sets “RS=True.”
• CS-RS
• Data transmission control
Hardware handshaking is performed between the MV and the PC. When the
CS signal becomes False while sending data to the PC, the MV stops the data
transmission. When the CS signal becomes True, the MV resumes the data
transmission. The MV treats the “X-OFF” and “X-ON” signals that are received from
the PC as data.
• Data reception control
The operation is the same as with XON-RS.
Note
• You must design the PC program so that the received buffer of neither the MV nor the PC
does not become full.
• If you select XON-XON, send the data in ASCII format.
